Reach 100!

Here is your challenge...

You must choose four different digits from 1−9 and put one in each box. For example:
Square divide into four, with 5,2,1 & 9 in the sections. 
This gives four two-digit numbers:
52 (reading along the 1st row)
19 (reading along the 2nd row)
51 (reading down the left hand column)
29 (reading down the right hand column)

In this case their sum is 151.

Your challenge is to find four different digits that give four two-digit numbers which add to a total of 100. Can you find 4 different numbers to put in the grid?

Think about:
Where could you start?
How do the four digits you choose contribute to the zero in the units column of 100?

      Remember Sumayah, you can only use 4 digits (1 per box), it is then these digits that make 4 different numbers.
